[Index Patterns] Use deprecation api for scripted fields #100781

Dosant · 2021-05-27T13:46:36Z

Summary

Close #97947
Scripted fields are deprecated. Runtime fields should be used instead. This pr adds information about this to the upgrade assistant. It hasn't been decided when scripted fields will be removed yet, hence keeping this as warning.

Release notes

Add scripted fields depreciation information to upgrade assistant

Checklist

Unit or functional tests were updated or added to match the most common scenarios

For maintainers

This was checked for breaking API changes and was labeled appropriately

How to test

I viewed upgrade assistant UI by tweaking the condition in the code

kibana/x-pack/plugins/upgrade_assistant/public/application/app.tsx

Lines 26 to 28 in 186b936

    
           if (isReadOnlyMode) { 
        
             return <ComingSoonPrompt />; 
        
           }

. Current functional test doesn't test the UI #100781 (comment), but it calls upgrade assistant API and checks that there is a part about scripted fields

src/plugins/data/server/index_patterns/deprications/scripted_fields.ts

+      if (indexPatternsWithScriptedFields.length > 0) {
+        // no need to look up all index patterns since we've found at least one that has scripted fields
+        await finder.close();
+        break;


I intentionally don't fetch all index patterns to make this function cheaper. This is reflected in the wording of the message below: You have **at least** <n> index patterns...

I think we should show a full list of index patterns that need updating as some setups may have a large number of index patterns and only a few might have scripted fields. We need a way to deliminate the index patterns as they can have commas in them. Could we link directly to the index patterns?

Could we link directly to the index patterns?

Nope, as I understand we can only use plain text.

At this moment this pr shows at max 3 index pattern titles as a hint.

Do you think we should show more out from the page? (e.g. in the current implementation we can remove that .slice(0,3) where I prepare the message

Or do you think we should fetch all the index patterns and show the whole list no matter how long it is?

In the current implementation user can:

Take a look at a message, see up to 3 index pattern titles that need to be fixed

Fix them

If there are more to fix, see another 3 index pattern titles and fix them

Not ideal, but not sure we want to fetch all the index patterns?

I updated so in the main message we show just up to 3 index pattern titles, but then when you open dialog with details we list all of them!

'data' is using a deprecated feature is an odd statement to show the user. Are we able to change this? Did core create this API? Would be nice if this could be improved.

@Bamieh do you think we should introduce some kind of caching in the deprecation service? atm everytime the /api/deprecations route is called, all the deprecation providers are executed, and I wonder if this will be alright when we'll have a lot that are performing ES requests like this one. wdyt?

If we do, not sure how it will work exactly? It is likely that with the cashing in place the use case I expressed in e2e testtest/api_integration/apis/index_patterns/deprecations/scripted_fields.ts might break?

Also @pgayvallet, I think having so many index patterns is more of an edge case and inside the app we simply currently do

kibana/src/plugins/data/common/index_patterns/index_patterns/index_patterns.ts

Lines 96 to 100 in 51616e1

const so = await this.savedObjectsClient.find<IndexPatternSavedObjectAttrs>({

type: 'index-pattern',

fields: ['title'],

perPage: 10000,

});

@Dosant this should not impact this PR, I was more wondering about long-term performances.

Initially i had caching in place for the service but it didnt make sense to keep it. The API is called only at the user's request when they open the UA or explicitly via the API. Generic caching wont work since we do not want to return already resolved deprecations from the api. We always want the latest state of the deprecations.

For performance it might make sense to introduce pagination rather than caching. The service would paginate the kibana deprecations so we dont have to loop over all deprecations every time. Since the deprecations are registered at setup in an array we can guarantee the order and create basic pagination from the public contract.

I agree with @pgayvallet this doesnt impact the PR. I'll open a separate issue to continue the discussion there.

I think we can't change this atm

I'm talking to @alisonelizabeth to see how this could be tested by QA. The UI for the deprecation service might not be available until 7.15. Considering how to proceed.

Looks good and works well, waiting to hear from Alison about how we want this to go through QA.

@mattkime we have this issue to improve this #99625

Looks good and works well, waiting to hear from Alison about how we want this to go through QA.

I'm trying to address this as well (context: #99043 (comment))

The service provided by core is testable although we do need UA to provide some tools to allow teams to run functional tests for their deprecations in the UA UI
